    Abstract: A scroll compressor includes an orbiting scroll member disposed within a compressor housing. The orbiting scroll member has a substantially circular baseplate and a generally spiral wrap extending from its base. A first seal is disposed proximal to the outer periphery of the orbiting scroll baseplate to provide an external seal between the baseplate and the housing. A second seal is disposed radially inward from the first seal to provide an internal seal between the baseplate and the housing. A space between the internal seal and the external seal defines a balance piston chamber. The balance piston chamber is pressurized via a high or intermediate pressure oil source to reduce thrust loading on the baseplate caused by an axial pressure differential across the baseplate.

    Abstract: A heating, ventilation, air conditioning, and refrigeration (HVACR) system is disclosed. The HVACR system includes a compressor, a condenser, and an evaporator fluidly connected to form a refrigerant circuit. A lubricant return line is fluidly connected to the compressor and to the evaporator. A pressure difference between the compressor and the evaporator induces a fluid flow of lubricant from the evaporator to the compressor.

    Abstract: A screw compressor, refrigerant circuit, lubrication method are disclosed. The screw compressor includes a suction inlet that receives a working fluid to be compressed. A compression mechanism is fluidly connected to the suction inlet. A discharge outlet is fluidly connected to the compression mechanism that outputs the working fluid following compression by the compression mechanism. The screw compressor includes a slide valve that is movable between a first position and a second position. The first position corresponds to a high volume ratio and the second position corresponds to a low volume ratio. The slide valve includes a plurality of lubricant passageways selectively connectable to a lubricant source. A first of the plurality of lubricant passageways is configured to be selected to provide lubricant at the high volume ratio, and a second of the plurality of lubricant passageways is configured to be selected to provide lubricant at the low volume ratio.

    Abstract: A compressor crankshaft assembly includes a crankshaft and an eccentric drive pin extending from one end of the crankshaft. The shape of the drive pin viewed into the exposed end of the drive pin is defined by the intersection of a first cylinder that is coaxial with the axis of a substantially cylindrical orbital bearing journaled and installed to receive the eccentric drive pin and a second cylinder that is coaxial with the axis of a substantially cylindrical main bearing journaled and installed to rotatably receive the crankshaft, such that the area defined by the intersecting portion is less than the area defined by either cylinder.
